A number of stars the likes of Juan Martin del Potro, Madison Keys, Sloane Stephens and more were not able to make their way to the 2017 Australian Open. While we mourn their missing-in-action status, it's time again to curate, celebrate and berate the styles on display at this major tournament. Without further ado, here comes the attire deserving boos:

Angelique Kerber's adidas outfit looked odd under her warmup gear, and then looked all the more odd when revealed. 

The drape-y ensemble's layers of sheer material create the effect that there's a lot going on. Too much. Something akin to neon maternity wear, an illusion this super-fit No. 1 star should not suffer. And though the drawn back over her shoulder blades provided a great touch, it can't save everything.

The same attire did in Anastasia Pavlyuchenkova, even as she marched forward a round from where Kerber herself fell out. In separates that gave the appearance of waves on a beach, both players drowned.

Svetlana Kuznetsova's hyper-perforated skirt was a drastic take on the breathable 2016 adidas trend, and overall her garb went awry by breaking at the same place on the hip on both her top and skirt.

As always, the ATP men are hardly exempt from becoming fashion-roundup prey, in addition to targets in the draw. Novak Djokovic, decked out in a winsome Uniqlo henley shirt, lost with his matching dark-gray shorts-and-socks combo. The bright adidas kicks wed to the socks made for a look straight off the dad rack.

Nike seemed to get lazy with Eugenie Bouchard's kit, opting to combine Serena's midriff-baring, Aussie-French 2016 look with her Melbourne 2017 dress, and more or less leave its young star to her own devices.

Dominic Thiem, keep doing you. I want to like his adidas getup—of note, worn by others in the adidas stable—but it's just too much of a good thing. Even so, he wields one of the most stylish and fun-to-watch arsenals in the men's game these days. The optimist believes he'll right the sartorial ship, too.

Asics outfitted the "I-feel-like-crap" CoCo Vandeweghe, vanquisher of Kerber in the fourth round, in a dress that looks like she rolled around for a while on Rod Laver Arena's freshly painted courts. Ad-out.

Fabio Fognini, now in Hydrogen, suffered a fate similar to that of Vandeweghe: The dominant color in a look should not be the same as the court surface's own hue.

Another offender in the monochromatic, same-sy, blue-on-blue department: Gael Monfils, swimming in Asics just like Vandeweghe.

Teed off: It's best to avoid self-referential T-shirts when meeting the press. As merch and as practice wear, have at it. Stan Wawrinka made a mistake akin to wearing a band tee to that band's concert. (Or, worse yet, it was as if the band wore its own merchandise table goods while performing on stage. Just say no.)

Venus Williams, in one of her two AO17 kits, appeared in a predominantly yellow top that drummed up the reminder of her lattice-worked abdomen at 2011's Melbourne event. Seems she'd want to forget that major, time and site of her first retirement from a Grand Slam singles match. Regardless, this EleVEn look rated more like a five. 

Donning Under Armor per usual, Andy Murray, forever a grand quote, continued to be a terrific bore as togs go.

It was not her fault, but you would be right to assume it also wasn't a timely homage to a recently retired colleague: Ying-Ying Duan showed up Down Under sporting Ana Ivanovic's 2016 US Open dress by adidas.

Yaroslava Shvedova and Ashleigh Barty's Fila look had far too many constellations in the print. Points for its funky quality, demerits for execution.

Worst Dressed

For Anastasija Sevastova, it was game-ova due to the clashing patterns that Yonex put her in. It's proper and ideal to mix it up and play with patterns. They just shouldn't be full-on feuding.

It's not all doom and gloom though, take a look at the Australian Open Fashion Aces.
